I INTERNAL-COMBIJ'STION ENGINE.

Specification of Letters Zlatent.

Application filed May 27, 1912. Serial No. 699,987.

To allwhom it may concern."

Be it known that "I, NORRIS C. WARD, a

citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Internal-Com bustion Engines, of which the following is a specification.

My invention relates to improvements in internal combustion engines and has for its object, the provision of an improved engine of this character, which is capable of producing two operative impulses on each revolution of the crank shaft of the engine, and in certain details of construction. The invention consists in the combinations and arrangements of parts hereinafter described and claimed. 7

The invention will be best understood by reference to the. accompanying drawingforming a part of this specification, and in which, I

Figure l is a vertical central section of an engine embodying my invention, and Fig. 2, an elevation taken at right angles to Fig. l, with portions shown in section, on line a-m of Fi 1.

The preferred form of construction,- as illustrated in the drawing comprises a suitable crank case 1 having a suitable crank shaft 2 rotatably mounted therein. A hollow. casing formed in two parts 3 and 3 is secured to crank case 1, and is provided with a water jacket space of ordinary form and construction, and water circulating pipes 4 adapted to produce a water circulation in said jacket. A reciprocating cylinder .5 is

mounted in casing 3 -3' and is connected by means of a connectlngrod 6 wlth crank shaft 2 as will be readily understood. Cylinder 5 is closed at both ends and its inner end is provided with two inwardly opening automatic valves 7 and its outer end with an inwardly opening automatic valve 8. A hollow stationary head 9 is secured in cylinder 5 and easing 3-3 by means of pipes 10 which are threaded in said casing and head and passed through suitable slots 11 provided in the walls of cylinder 5. The pipes 10 thus serve as a means for circulating water through head 9 to cool the same. Spark plugs 12 are provided for each end of cylinder 5, the same being secured in casing 3-3 and passed through suitable slots 13 in the walls of cylinder 5, said spark plugs being provided with any usual or de-- cations, an

sired form'of electric connections for producing the'sparks at the. proper times, as

will be readily understood by those skilled in the art. Fuel supply pipes 14 lead into each, end of easing 3-3, the openin s or portsat the inner ends of said pipes eing controlled b said pipes having the usual forms of carbureters or other source of fuel supply. Exhaust pipes 16 are also provided 1n casing 3 -3 adjacent each end of head 9 andsuitable exhaust ports 17 are provided in the walls of cylinder 5 to register with pipes 16 to exhaust the respective ends of cylinder 5 at the proper times, as will be reztidily understood by those skilled in the ar 1 By the arrangement set forth it will be observed that as cylinder 5 reciprocates an explosive mixture wilLbe alternately drawn into crank case 1 and the space 15 in the outer end of casing 3 3. These mixtures are alternately compressed by the next movement of cylinder 5,-so that when exhaust takes place from the respective ends of cylinder 5, valves 7 and 8 will automatically Patented Nev. 18, 1913.

cylinder 5 during its reciproopen to admit said mixtures to thecorresponding ends of cylinder 5. The arrange ment thus constitutes at each end of cylinder 5 a two-cycle engine cylinder opposed in operation to the other end so that two explosions will be obtained at every revolution as will be readily understood by those skilled in the art.

The specific form of construction illustrated will be found to be simple and effective in use, and readily cooled to guard against overheating.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to'be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims. s I

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1.,An internal combustion engine comprising a hollow casing; a cylinder mounted to reciprocate insaid casing-and closed at each end, a hollow'stationaryhead secured in said cylinder by means of water pipes passing through said casing and cylinder, said cylinder being slotted to permit reciprocations thereof; means for admission and exhaust for each end of said cylinderand means for utilizing recip'rocations of said cylinder, substantially as described.

2. An internal combustion engine com prising a hollow casing; a cylinder mounted end of said cylinder, said cylinder being slotted to receive said means of ignition and permit reciprocations of said cylinder and means for utilizing reciprocatlons of said cylinder substantially as described.

3. An internal combustion engine comprising a hollow stationary head provided with water circulating means; a cylinder mounted to reciprocate on said head and closed at each end; a casing surrounding said cylinder and provided with a water jacket; means for admission and exhaust for each end of said cylinder; means for ignition for each end of said cylinder; and

means for utilizin reciprocations of said cylinder, substantially as described.

4. In an internal combustion engine, a closed crank case; a crank shaft in said case; a hollow casing secured .to said crank case in open communication therewith; a cylinder mounted to reciprocate in said casing and having closed ends; a connecting rod conwardly opening valves in the ends of said cylinder; fuel supply connections for the 0pposite endspf said casing and arranged to be opened and closed by said cylinder; ex-

haust connections in said casing for the ends of said cylinder, there being exhaust ports in the walls of said cylinder adapted to register therewith; means of ignition for the ends of said 0 linder; and a stationary head in said cylin er and secured to said casing, there being slots in the walls of saidcylinder to accommodate the securing means, substantially as described.

5. In an internal combustion engine, a closed crank case, a crank shaft in said case; a hollow water jacketed. casing secured to said crank case in open communication therewith; a cylinder mounted to reciprocate in said casing and having closed ends; a connecting rod connecting said cylinder and crank shaft; inwardly opening valves in the ends of said cylinder; fuel supply connections for the opposite ends of said casing and'arranged to-be opened and closed by said cylinder; exhaust connections in said casing for the ends of said cylinder, there being exhaust ports in the walls of said cylinder adapted to register therewith; means of ignition for the ends of said cylinder; and a stationary h'ollow head in said cylinder and secured to said casin there being slots in the walls of said cyl nder to accommodate the securing means, and said securing means also constituting means for effecting a water circulation through said head, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. necting said cylinder and crank shaft; in-
